Guan Fengji emerges as the foster daughter of Guan Yu, sworn brother to Liu Bei. Her presence within the historical conflicts arrives unexpectedly, facilitated by the mystic Taoist Zuo Ci. Both Zuo Ci and Fengji herself hold fast to the belief in her biological connection to Guan Yu, even as the narrative firmly positions her as his adopted child. A romantic bond forms between Fengji and Ma Su, the military strategist serving Kongming (Zhuge Liang). This relationship introduces a deeply personal layer to the grand historical stage, contrasting with the dominant political and military strategies. Her connection to Ma Su inevitably draws her into the sphere of Kongming's campaigns and their far-reaching consequences. Fengji's personal journey unfolds against the prolonged devastation of the Three Kingdoms wars. The narrative sets her story – encompassing her relationship and questions of lineage – against the backdrop of sweeping tragedies and the decline of pivotal figures. This framing utilizes her experiences to reflect the profound human toll exacted by the era's relentless conflict and ambition. Her character arc remains contained within this specific Sangokushi adaptation, concluding with the events leading towards the culmination of the Three Kingdoms period's most decisive phase.
